14+ how sad about Logan. I hope your tenant finds the best way for him to deal with this situation. One thing that strikes me about starting Glucosamine is that it takes weeks before it really starts to work. It won't hurt to start him on it, and may help, but it might take longer than the end of January before Logan shows any improvement. :sad:
You are wonderful
to try to help your tenant with Logan but I know it is very hard to watch an animal in pain and not try to do something.
